Minimally used XKitz 2way active crossover, the pair of boards (stereo). Change freq via pluggin resistor modules, there's a calculator on their site somewhere along with the latest manual. Has level trimpots for high and low as well as a BSC shaper - refer to manual.
Sounds great, works well. Includes what you see, the 2 modules mounted to board with barrel dc jack. Provide your own 12-24V wallwart. Also pay attention to having one jumper set that isolates the signal ground from power ground. Just not going to use, do more passive crossover stuff than active these days.
